Put squash halves, cut side up, on a microwave safe plate or dish. Place 2 tablespoons butter and 2 tablespoons brown sugar into the cavity of each half.
Cook in the microwave on full power until flesh is soft, 8 to 10 minutes. Rotate squash a couple of times to ensure even cooking.
Scoop out flesh along with sugar and butter and place into a medium bowl. Mash slightly to blend.
Serve in a bowl or in the squash shells.
